The opposition leaders have stated that Euromaidan protest activists' roadblocks in Kyiv streets have been attacked.

"They are storming our roadblocks," Svoboda Party leader Oleh Tiahnybok said at a press conference at the national resistance headquarters on Monday.

He said that the main attacks were directed at the roadblocks organized by the activists around the site of the protest.

"A picket has been beaten," leader of the Batkivschyna faction Arseniy Yatseniuk said.

The stance of pro-EU activist protesting at Independence Square remains unchanged, Yatseniuk said. "We do not beat policeman, we do not use force, we do not have any weapons and we do not have any special means," he said.

If law enforcement authorities use force, this will have "unpredictable consequences," Yatseniuk said.

The Interior Ministry's special purpose units want free access to Bankova Street so that Ukrainian President Viktor Yanukovych can pass, the opposition leaders said.

"As to freeing streets for Viktor Yanukovych to pass, as we have said: pickets are held throughout Kyiv but everyone can walk to work. This is how the government got to work and it is necessary for the president to walk on foot too in order to meet with the U.S. Under Secretary of State," Yatseniuk said.
